XmtIML[7:0]
Name
T_UIIML—Transmit UTOPIA Interface Initiation Minimum Level
((000)51H)
This register configures the transmit UTOPIA interface features that are common to the four
channels.
XmtIML[7:0] configures the minimum level of data the transmit FIFO
must contain to initiate the transmission of a new packet (to read the
first word of a packet). XmtIML[7:0] are used to avoid consecutive
FIFO underflows. They are only considered when a new packet is
going to be transmitted and there is no complete packet in the FIFO,
and XmtFifEmptEOF = '0'. If the FIFO contains an EOF, the
transmission starts regardless of the IML value and the amount of data
in the FIFO. The contents of XmtIML[7:0] indicates the number of 16-
word blocks (64-byte blocks).
Channels 1, 2, and 3: The size of the FIFO is 512 words of 32 bits
(2048 bytes) and only XmtIML[4:0] are used (XmtIML[7:5] are unused
bits). XmtIML[4:0] sets one of 32 different minimum levels:
0000 = Initiate Tx if FIFO contains 1 or more words.
0001 = Initiate Tx if FIFO contains 17 or more words.
0010 = Initiate Tx if FIFO contains 33 or more words.
……
1110 = Initiate Tx if FIFO contains 481 or more words.
1111 = Initiate Tx if FIFO contains 497 or more words.
Channel 0: The size of the FIFO is 4096 words of 32 bits (16-Kbytes)
and XmtIML[7:0] sets one of 256 different minimum levels:
00000000 = Initiate Tx if FIFO contains 1 or more words.
00000001 = Initiate Tx if FIFO contains 17 or more words.
00000010 = Initiate Tx if FIFO contains 33 or more words.
……
11111110 = Initiate Tx if FIFO contains 4065 or more words.
11111111 = Initiate Tx if FIFO contains 4081 or more words.
